About Converting Nanowatts to Ronnawatts
Nanowatt and Ronnawatt both describe power output, and the conversion is a routine part of comparing an engine or motor's spec sheet across countries that use different power units. Specifically: Nanowatt is 1e-9 watt units, and ronnawatt is 1e+27 watt units.
Formula
ronnawatts = nanowatts × 1e-36
This factor comes from each unit's defined relationship to the category's base unit: 1 nanowatt equals 1e-9 base units, and 1 ronnawatt equals 1e+27 base units, so dividing one by the other gives the direct nanowatt-to-ronnawatt factor of 1e-36.
Simple example
1 nW × 1e-36 = 1e-36 RW
1 nanowatt = 1e-36 ronnawatts.
Real-world example
100 nW × 1e-36 = 1e-34 RW
100 nanowatts = 1e-34 ronnawatts.

Reverse conversion: Ronnawatt to Nanowatt
1e-36 RW × 1e+36 = 1 nW
1e-36 ronnawatts = 1 nanowatts.
nanowatts = ronnawatts × 1e+36

Frequently asked questions
How many ronnawatts are in 1 nanowatt?
1 nanowatt equals 1e-36 ronnawatts, using the exact defined conversion factor rather than an estimate.
How do I convert nanowatt to ronnawatt?
Multiply the nanowatt value by 1e-36. The converter above does this instantly to whatever precision you set.
How do I convert ronnawatt back to nanowatt?
Use the reverse factor: 1 ronnawatt equals 1e+36 nanowatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanowatt?
Nanowatt (nW) is a unit of power.
What is a ronnawatt?
Ronnawatt (RW) is a unit of power.
Is the nanowatt to ronnawatt conversion exact?
Yes. Both nanowatt and ronnawatt are defined by fixed standards rather than physical artifacts, so the factor of 1e-36 used above is exact to as many digits as you choose to display.
